  1. process of distributing genetic material
    mitosis
  2. scientist who noticed threadlike structures in cells during cell division
    Walther Flemming
  3. etymology of mitosis
    • mitos - threads
    • osis - condition of
  4. pinching in of the cell membrane and eventual split of the membrane and its contents into two daughter cells
    cytokinesis
  5. when does cytokinesis occur
    about the same time (or just after) the last phase of mitosis
  6. circular patterns of organisms' life histories
    life cycles
  7. life cycle of humans
    • conception
    • development
    • adulthood
    • reproduction
  8. Interphase parts
    G1 or Gap 1 - growth and normal metabolic roles

    Synthesis - DNA replication

    G2 or Gap 2 - Growth and preparation for mitosis
  9. period between cell divisions
    interphase
  10. what replicates during interphase
    chromatin
  11. what are formed during interphase in anticipation of division
    additional cell fluid and organelles
  12. phase where the nuclear membrane disappears
    prophase
  13. phase where the centriole pairs move to opposite poles of the cell as spindle fibers begin to project from them
    prophase
  14. phase where the chromosomes arrange themselves singly as a thin sheet along the cell's equator
    metaphase
  15. imaginary center plane
    equator
  16. phase where the chromatids split at the centromere and move toward opposite poles along the paths of the spindle fibers
    anaphase
  17. phase where each pole of the cell has a full group of 46 single chromosomes
    anaphase
  18. phase where each side of the cell changes everything to the way it should be during interphase
    telophase
  19. phase where a nuclear membrane forms around each group of chromosomes
    telophase
  20. phase where the chromosomes uncoil to form long chromatin strands
    telophase
  21. phase where the remnants of the spindle fibers disintegrate
    telophase
  22. what does each daughter cell gain from the parent cell
    roughly half of its cytoplasm and organelles
  23. does each cell division vary? how?
    the length of time between divisions and the time required for division to take place, varies considerably from cell to cell
  24. range of the time for cell division
    20 mins. to several hours
  25. lab specimen used
    whitefish blastula
  26. blastula meaning
    embryonic hollow ball of cells
  27. developmental stage in the growth of many animals
    blastula
  28. why choose whitefish blastula
    its cells undergo rapid cell division so we can see many cells at various stages of the cell life cycle
  29. phase where chromosomes pair up through centromeres
    interphase
  30. phase where centrioles go to opposite ends of the poles
    prophase
  31. phase where the nucleolus and the nuclear membrane dissolve
    prophase
  32. type of cell division that occurs during the formation of reproductive cells (sperm and eggs)
    meiosis
  33. magnification used
    1000x
  34. phase where spindle fibers appear
    prophase
  35. tiny bodies of connected DNA molecules
    chromosome
